The separation of the two nuclei present in a pair occurs only if their Coulomb barrier can be overcome. The barrier, similar to that involved in the alpha particle emission, has to be corrected for the sphericity of the products. We have shown that only two pairs of 258Fm have a fission energy greater than their barrier [1]; all the others are confined. A nucleus can fission symmetrically only if the mass of its light product becomes equal to 126. It may be asked why 252Cf fissions asymmetrically, although a light product of mass 126 could be formed in the interaction of its 44S cluster with the bare 82-proton phase: the reason is that 126In - 126In is still confined. We propose a rational definition of the fission barrier; it is the difference between barrier Bc and fission energy Q. With our discovery of the superheavy boson, we have confirmed that fission is really a cataclysmic rearrangement. [1] G. Mouze, Bormio Intern.Winter Meeting, Università di Milano, 2005.
